Back in December, we mentioned that some overzealous pornography filters in the UK that were meant to keep kids from seeing pornographic materials were flagging some legitimate and non-porn related sites. Specifically, the filters were blocking a number of sites for charities and sex education in the filter.

The UK government is trying to unblock these legitimate sites with the creation of a website whitelist. Many of the sites on the list are run by charities that want to educate kids about health, sex, and drug addiction.

The government wants to set up a system that will let any website that thinks it is being blocked wrongly to tell the ISP their story and perhaps be added to the whitelist.

"Research suggests the amount of inadvertent blocking is low," said David Miles, who chairs the working group on over-blocking for the government's UK Council for Child Internet Safety.

Miles has been working with research on accidental blocking by the filters and visiting the charities to determine how to get the filters to block pornographic material without blocking the legitimate sites.

The list will be shared with ISPs that run the network level filters to ensure these sites are viewable.
